SPECIFICATION forming part of Letters Patent No. 512,507, dated January9, 1894. Application filed April '7. 1893. Serial No. 469,386. (Nomodel.)

To a/ZZ whom t may concern.-

Be it known that I, CHARLES' E. O. EDEY, a subject of the Queen of GreatBritain, and a resident of Des Moines, in the county of Polk -and Stateof Iowa, have invented an Improved Oar-Coupling, of wlich the followinged out in my claims and illustrated in the ac= companying drawings, inwhich Figure 1 is a top view of one of the couplers applied to a portionof a car. Fig. 2 is a side view of the bolt for securing the draw bar tothe car. Figs. 3 and 4 are horizontal sectional views of the draw head,showing the vertical jaw in different positions. Figs. 5 and 6 are viewsof the vertical jaws showing face and top views thereof. Fig. 7 is afront, face view of the same, with the vertical jaw removed. Fig. 8 is aperspective view of the gravity latch. Fig. 9 .is a perspective view ofthe lever for operating the gravity latch. Fig. 10 is a perspective Viewof the complete coupler applied to a car.

yReferring to the accompanying drawings, the reference letter A is usedto designate the draw bar, and A2 the draw head the outsideconformationlof which is of the ordinaryshape. This draw bar isconnected wit-h the car by means of a bolt B extended through the drawhead to a point in the rear of the rear end of` the draw bar, through alongitudinally elongated slot. The head of this bolt has a verticalconvex face B3 to engage a partition C formed on theinterior ofthe drawbar in proximity to the draw head to serve as a pivotal point in whichthe draw-bar may turn. A plate C2 at the rear end of the draw bar has aconcave face to receive the rear end of the draw bar and allow it tomove horizontally relative thereto.

C3 is a coil spring of the usual kind encircling the rear end of thebolt B and normally exerting its pressure forwardly upon the plate C2which .plate is also provided with a horizontal slot to admit said bolt.

D designates a vertical jaw pivoted in one side of the draw head andhaving a rear extension D2 adapted to enter the cavity in the draw head.A straight vertical shoulder D3 formed upon said rear extension comes inproximity to the opposite side of the cavity from the pivotal point ofthe vertical jaw and is adapted to pass some distance in the rear of theforward face of the draw head.

F designates a gravity latch placed in a cavity formed in the draw head,which cavityT is extended outwardly and slightly rearward from the innerface of the cavity in the draw lhead and its bottom is inclineddownwardly,y toward the bottom of the draw head cavity. Said latch isprovided with a vertical shoulder F2 on its front face and an inclinedsurface F3 on its bottom to engage the i11- clined bo'ttom of itscavity. An inclined surface on the lower end portion of the gravitylatch provides means whereby the rear extension of the draw bar willraise said latch and pass behind it and the latch automatically drop infront of the shoulder of the rear extension to look the vertical jaw.The top of the latch or block is also inclined as required to correspondwith the inclined roof of the cavity in which it operates.

Means are provided for elevating the latch to release the vertical jawas follows: H designates a lever p ivotally mounted upon the bottom ofthe draw head cavity with one of its ends in proximity to the gravitylatch. This end has an inclined face H2 adapted to be forced between thegravity latch and the bottom of the draw head cavity to elevate theformer and force it upwardly and outwardly in its cavity to allow therear extension of the vertical jaw to pass beyond it. This lever isactuated by a second lever .I which is passed through the sides of thedraw head, pivoted to the bottom of the drawhead cavity with its innerend in engagement with the lever H so that arearward movement of thelever J will bring the inclined face of the lever H into engagement Withthe gravity latch to elevate it and release the vertical jaw. Asbefore 1. An improved car coupling comprising the following elements, towit: a suitable draw bar, a draw head formed thereon, a vertical jawpivotally mounted inisaid drawhead and having a rear extension adaptedto enter the draw head cavity, a gravity latch having an inclined bottomin a cavity in the draw head opposite fromthe pivotal pointofthevertical jawgadapted to .be automatically moved ,bytheirearextension of the vertical jaw to allow said extension to passbehind it and then automatically drop into position'in advance of therear extension to lock the vertical jaw `and ,lneansffor engagingtheinclined bottom ofthe 'latchto elevate the latch and freethe jaw, as

required in u ncoupling.

72. An mprovedcar coupling comprisingthe following elements, to wit: asuitabledraw bar, a" draw head formed thereon, a vertical jaw Dpivotally mounted in said draw `head `and provided with a rear extensionD2 having a vertical' shoulder D3 as set forth, a gravity latch `Fhaving a shoulder F2 and an inclined bottom `Fl placed in a cavity inthe side of the draw head as set forth, a' lever H pivoted toth'efbottom of the draw head cavity and provided with the inclined faceH2, alever .l extended through the siderot the draw head pivoted to thebottom of the draw head cavity to engage the lever H, substantially asset forth, for the purposes stated.

y3.1In a car coupling,the combination of the following M'elements, asuitable draw head, a

hollow draw 4bar extended rearwardly therefrom, a bolt pivotally mountedin the approximate, transverse center of the draw bar, ex-

tended through the rear end thereof and attached to the car,substantially in the manner `set forth forthepurposes stated.

4. An improved car coupling comprising the following elements incombination, to wit: a suitable draw bar A having a draw head A2thereon, a bolt B extended .through said draw Ibar and provided withahead B2 to engage aA shoulder C'formed on the interior of thedraw 'barVas set lforth, a vertical'jaw D pivotally mounted in said drawfh'ead andprovided with va rear extension Dzhavinga vertical shoulder D3 as setforth, a gravity latch yF' vhaving a shoulder Fitand an inclinedbottomF3 placed in a cavity; in the side of the draw head asset forth, aleverH pivoted-to the `bottom of the draw head cavity and provided withthe .-inclined facelHz, alever J extended through the side of the drawrhead cavity togengagenthe :lever H substantiallygin themannerfsetlfforth for the purposes stated. i
